<b>Abstract</b>— <p>Specific patterns of lipid distribution in cell membranes determine their structural and signaling roles and ensure the integrity and functionality of the plasma membrane and cell organelles. Recent advances in the development of recombinant lipid biosensors and imaging techniques allow direct observation of the distribution, movement, and dynamics of lipids within cells, significantly expanding the understanding of lipid functions and their involvement in cellular and subcellular processes. In this review, we summarize the data related to the development and application of recombinant protein sensors for various lipids in cell membranes.</p>
